Hi Everyone,
I’m using Java plug-in API (plugin.jar which is present in JAVA_HOME/jre/lib
folder) for fetching the proxy server details like host and port of the
proxy server and Apache HttpClient API for fetching the proxy is
authenticated or not.
I used the below code for detecting the proxy authentication details and
this code is working fine and showing me the desired results.
private void detectAuthentication() {
try {
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", hostName);
System.setProperty("http.proxyPort", "" + port);
ProxyClient proxyClient = null;
ConnectMethod connectionMethod = null;
try {
setProxyProperties();
proxyClient = new ProxyClient();
proxyClient.getParams().setConnectionManagerClass(SimpleHttpConnectionManager.class);
HostConfiguration hostConfiguration =
proxyClient.getHostConfiguration();
hostConfiguration.setHost(UtilConstants.HTTP_PROXY_DETECT_URL);
hostConfiguration.setProxy(hostName, 80);
System.out.println("before connect");
ProxyClient.ConnectResponse response = proxyClient.connect();
System.out.println("after connect");
connectionMethod = response.getConnectMethod();
isProxyAuthenticated = connectionMethod.getDoAuthentication();
System.out.println("isProxyAuthenticated : " +
isProxyAuthenticated);
AuthState authState = connectionMethod.getProxyAuthState();
isAuthAttempted = authState.isAuthAttempted();
System.out.println("isAuthAttempted : " + isAuthAttempted);
isAuthRequested = authState.isAuthRequested();
System.out.println("isAuthRequested : " + isAuthRequested);
schemaName = authState.getAuthScheme().getSchemeName();
System.out.println("schemaName : " + schemaName);
}
catch (Exception e) {
System.out.println("" + e.getMessage());
isProxyAuthenticated = false;
}
finally {
if (proxyClient != null) {
proxyClient = null;
}
if (connectionMethod != null) {
connectionMethod = null;
}
}
}
catch (Exception e) {
isProxyAuthenticated = false;
}
}
When using the same code in a bean class then it’s not working and it’s
throwing the exception. I could understand that apache proxy client is
trying to connect to the Socks server, but socks server details are not
present in the system properties.
